摘要 |
Disclosed is a method (Fig. 4) and apparatus (Fig. 3) for an electrochemical impedance measurement, and in particular circuitry and components employed for such measurements. The system employs an injected broadband AC signal (Fig. 1) to produce an associated response signal (Fig. 2). The subsequent analysis of injected and response signals, considering both magnitude and phase, gives broadband impedance and therefore fluid characteristic information. An embodiment described is relative to a smart oil sensor system (Figs. 3, 6A - 6C) suitable for sensing, analyzing and reporting the condition of oil or other liquids used in equipment and machinery. |
